A system for locally authenticating a transaction of digital financial assets, such as cryptocurrency. A first device may locally store financial assets in non- volatile memory of the first device. The first device may use the locally-stored financial assets to conduct a local transaction with a second device. The first device may generate a transaction settlement data token and exchange the token with the second device, wherein the transaction settlement data token includes information specific to the local transaction, a value associated with the local transaction, and encrypted personal information associated with the first device. After receiving a confirmation of transmission from the second device, the value associated with the local transaction may be debited from the locally-stored financial assets.
